1 Claim.

This invention relates to buildings for storing and vending ice and has for one of its objects the provision of an ice storage compartment having special means for insulating the interior of the compartment from atmospheric heat.

Another object is to provide a wall structure surrounding the compartment having special means for retaining insulating substances, whereby the substances are prevented from separating.

A further object is to provide a roof structure for the compartment having special means for circulating and removing air above the compartment and beneath the roof whereby heat absorbed and radiated inwardly by the roof is absorbed by the moving air and is thus prevented from being absorbed by the upper portions of the compartment.

Other objects will appear in the following description and drawings, in which- 20 Fig. 1 is a perspective view showing the exterior of a compartment as the same would appear when constructed according to the principles hereinafter set forth;

Fig. 2 is a similar view showing a modified construction of the same;

Fig. 3 is a fragmental sectional elevational View showing the general features of wall and roof construction which will be described;

Fig. 4 is a similar view showing a modified form of roof; and

Fig. 5 is a sectional View showing details of wall construction which will be described.

Referring to the drawings, Fig. 1 discloses a compartment l0, set upon suitable corner posts II, having a platform portion l2, an insulated door [3 leading to the ice compartment, another door [4 leading to an ofiice or tool compartment and a dome fashioned roof l5 which will be referred to again shortly.

Fig. 2 discloses a compartment having a more simple form wherein the ice compartment is similar to that of Fig. 1 minus the platform l2 and extra compartment served by door I4. Further, the roof form and ventilating means is somewhat modified, as will be explained.

Details of construction of the compartment shown in Fig. 1 are clearly shown in Figs. 3 and 5.

The wall structure generally comprises sheathing members l6 and I1 suitably built up to form a hollow structure, there being a course of sheet material l8 underlying the sheathing.

That portion lying between the sheathing is stuffed with insulating material such as granulated cork. Any other material may be used.

The vertical portion of the walls are pro- 1934, Serial No. 716,228

vided with slanted partition members l9 suitably spaced apart and lying parallel with the floor of the compartment.

The function of members I9 is to divide the wall into a series of separate compartments each having a portion overlying an adjacent compartment, as at 20 and 2|.

It is well known that materials such as may be used for filling walls, even when placed therein with great care, will eventually settle some- 10 what, which settling action will result in formation of unoccupied areas in the walls with consequent loss of insulating value.

With the novel structure just described, settling of the insulating material will result in 15 formation of an empty pocket as at 2|, without, however, entirely breaking the wall of insulating material interposed between the wall surfaces.

In view of the foregoing, it will be apparent that my wall construction differs from the con- 20 ventional in that it provides a means for increas- 1 ing the useful life of the insulation.

Anadditional novel feature of my invention is disclosed in Fig. 3, wherein the roof I5 is shown so fashioned and dimensioned as to form a hollow dome-like top with its edges extending beyond the walls of the compartment as at 22. In the central portion is a ventilating duct 23 communicating between the interior and exterior of the dome. 30

The top wall of the ice compartment, 25, is provided with conventional insulation as shown. and the dome top provides an open area above the ice compartment.

Heated air accumulating under the dome is discharged by natural displacement through duct 23. Replacement of discharged air is accomplished through the open area at 22. The arrows clearly indicate the air movement.

In the above described manner, air is constantly circulated under the dome and is available to absorb and carry away heat absorbed by the roof and radiated inwardly. By this means a large portion of the heat which would normally accumulate under the dome is absorbed and removed.

The absorption of the heat by the top wall 25 and its penetration into the upper portion of the ice compartment is effectively lessened.

The principles above described are utilized in the form of compartment shown in Fig. 2.

Wall construction is identical with that shown in Fig. 3 and the air circulating feature is similar, with the exception that a duct or ducts 24 are provided at either end of the structure adjacent the highest point of the roof. It will be apparent that the same principles are used in both forms of roof, the'only difference being in the form and location of discharge duct. The roof structures may be used interchangeably as dictated by manufacturing considerations.

What I claim is:

An ice storage depot having an ice compartment provided with insulating walls comprising continuous inner and outer wall portions spaced apart, partitions disposed between said walls in such a manner as to divide the area between said wall portions into a series of separated horizontally disposed compartments, the area of each 5 compartment overlying that of adjacent compartments, and insulating material occupying the area of said compartments.
